Multimedia Data Transmission Synchronization Across Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia data transmission methods fail to transmit data and pictures synchronously between video networks and private networks, leading to security and confidentiality issues due to reliance on third-party platforms for data ferrying.
Innovation Solution
A method and device for encoding multimedia file descriptors and files into a unified format, allowing them to be transmitted and resolved securely across networks, ensuring synchronous transmission and maintaining data confidentiality by using a predetermined rule unknown to third-party platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data and pictures are transmitted separately through third-party platforms, then transmission can be achieved between video network and private network, but synchronous transmission cannot be ensured and security is compromised
Solution Approach 1:
The patent merges the transmission of data and pictures into a single unified process. The encoding unit encodes both data and corresponding picture into one multimedia transmission file, and the decoding unit decodes them together, ensuring they arrive synchronously at the receiving end without requiring separate transmission channels or third-party platforms.
Solution Approach 2:
The patent introduces an encoding unit and decoding unit as intermediary components that transform the transmission format. These intermediaries package data and pictures together in a standardized format for transmission, and then unpack them at the receiving end, enabling direct peer-to-peer transmission while maintaining compatibility and synchrony.
2Adaptability or versatility
If third-party platforms are used for data ferrying, then data transmission between networks is enabled, but data confidentiality and security are reduced
Solution Approach 1:
The patent extracts and eliminates the third-party platform intermediary from the transmission process. By establishing direct encoding and decoding units between the video network and private network, the system removes the security vulnerability of third-party data access while maintaining network compatibility through standardized encoding formats.
Solution Approach 2:
The patent segments the transmission system into independent encoding and decoding units that operate directly between networks. This segmentation removes the need for a centralized third-party platform, allowing each network to maintain control over its data while achieving compatible communication through standardized interfaces.
3Ease of operation
If separate transmission channels are used for data and pictures, then transmission flexibility is maintained, but data integrity and synchrony are lost
Solution Approach 1:
The patent combines data and picture transmission into a single integrated stream. The encoding unit packages them together with associated metadata, transmits them as one unified multimedia transmission file, and the decoding unit extracts them together, ensuring they remain synchronized throughout the transmission process while maintaining operational simplicity.
